Application filed April 29, 1914;. Serial Ito. 835,211.

To all whom it may concern Be it known that we, Rosana: F. BURKE and J OHN E. CRAVEN, citizens of the United States of America, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Tmprovements in Attachments for Displacement-Lubricators, of which the following is a specification.

This invention relates to lubricators, and more especially, to those of the displacement type.

The objects of the invention are to provide a simple, cheap and eliicient attachment for such lubricators whereby water may be quickly and easily introduced into the sight-feed glass, oil at the same time being cut ofl therefrom, for the'purpose of removing the collection of oil from said glass and delivering the same to the part to be lubricated.

With these and such other objects in view as may hereinafter more fully appear, our invention consists in the novel construction and arrangement of parts set forth in the specification, more particularly pointed out in the claims, and which are shown in the accompanying drawings, wherein Figure l is a vertical sectional view of a lubricator with our attachment in place thereon. Fig. 2 is a vertical sectional view of the attachment showing the same in its water admitting position. Fig. 3 is a detail perspective view of the conical valve. Fig. A is a perspective view of the valve casing.

Referring to said drawings by numerals, an oil cylinder, or tank 1 of any usual and preferred form, is provided with the usual attachments, such as the sight gage 2, sup ply reservoir 3 and oil discharge pipe 4:. The lower end of discharge pipe 4 is suitably fastened in a bore 5 formed in a cylindrical connecting member 6, forming part of the valve casing. Member 6 is threaded at its outer end and is adapted to be screwed into a hub 7, provided on the tank 1. The main, or body portion of the valve casing, shown at 8, is preferably square in cross section and is provided with a centrally located conical bore 9, into which the bore 5 and a bore 10, both formed in member 6, lead. Valve casing 8 is further provided with an outwardly projecting cylindrical portion 11, threaded to receive a collar 12, which is adapted to retain the lower end of the sight-feed tube 13, the upper end of which is similarly secured to the pipe lead ing to the part to be lubricated.

A cone shaped rotary valve 1 1, has a close turning fit in the bore 9 and is retained therein by a lock nut 15 which engages the upper end of said valve. Valve 14 is formed with a central bore 16 and is internally threaded throughout a portion of its length for the purpose of receiving and retaining the needle valve 17, the pointed end of which is adapted to be seated on the inwardly drawn end 18 of valve 14. At suitable points in the sides of valve 14: two ports 19 and 20 are formed; the former being adapted to register with the oil receiving bore 5 and the latter with the lower, water receiving bore 10. Valve 1 1 is further provided with a squared portion 21, having contiguous thereto the threaded portion 22, adapted to receive a screw cap 23 which locks in place a handle 24, the enlarged head 25 of which is provided with a square aperture to receive the square portion of the valve.

The operation of the device is as follows: The device being set as shown in Fig. 1 with the port 19 registering with bore 5, oil will flow through pipe 4-, bore 5, port 19, bore 16, and discharge from the point of needle valve 17. The oil, being lighter than the water in tube 13, will rise through said tube and be delivered to the part or parts to be oiled. Should oil become collected in tube 13, as often happens, handle 24: is thrown over turning valve 14: to the position shown in Fig. 2, with the port 20 registering with bore 10. As a certain amount of water is always present at the bottom of tank 1, water will flow through bore 10, port 20, and bore 16, to the tube 13 floating the oil therefrom. When the oil is floated from the tube the valve 14: is turned back to its oil delivering position.

Having described our invention, what we claim as new and desire to secure by Letters Patent, is

1. In a displacement lubricator, a tank, a sight-feed, a valve casing connecting said tank and sight-feed, bores in said casing for the admission of oil or water, a valve within said casing provided with ports registering alternately with said bores, and mechanism carried by said valve for controlling the amount of flow.

2. In a displacement lubricator, a tank, a sight-feed, a valve casing connecting said tank and sight-feed, bores in said casing for In testimony whereof we hereunto afiix the admlsslon of 011 or water, a valve 1n send our signatures 1n presence of two witnesses.
